Special Issue Information

Dear Colleagues,

The role of unmanned aerial vehicles (UAVs) in next-generation wireless networks and the Internet of Things (IoT) has recently gained significant attention. Two complementary research directions have emerged: (a) the design of future wireless networks providing ubiquitous and reliable connectivity to a network of UAVs and (b) UAVs complementing the existing wireless network infrastructure. Networked UAVs have vast applications ranging from delivery, remote surveillance, rescue missions, and inspection. However, operational success depends on the ability to operate UAVs in beyond visual line of sight (BVLoS) conditions. Therefore, existing wireless networks need to be optimized, and to an extent re-designed, to accommodate these aerial users. In the latter research area, due to their inherent flexibility, UAV-mounted access points, base stations, or relays can augment the existing fixed wireless network infrastructure. Such networks offer the flexible deployment of radio resources when and where they are most needed. Use cases include disaster recovery scenarios, search-and-rescue operations, the servicing of temporary cultural/sporting events, on-demand hotspot coverage, and IoT data harvesting for smart cities, agriculture, etc.

This Special Issue aims to share the progress and efforts being made by researchers in UAV networks. Special emphasis is given to soliciting novel concepts and transformative design ideas that are emerging in this area which lie at the crossroads of wireless networking, robotic navigation, and sensing.

Authors are encouraged to submit original research papers and review articles on a wide range of topics including, but not limited to:

  • Cellular connected UAVs;
  • Connectivity for UAV corridors in aerial mobility;
  • UAV-enabled Open Radio Access Networks (O-RANs) ;
  • Localization and sensing with UAVs;
  • Prototypes, testbeds, and experimental results;
  • 3D radio mapping with UAVs;
  • UAV energy-efficient trajectory planning;
  • Machine learning for UAV-aided wireless networking ;
  • Data harvesting with UAVs in IoT networks;
  • UAV mesh networks.

This paper applies federated reinforcement learning (FRL) in cellular vehicle-to-everything (C-V2X) communication to enable vehicles to learn communication parameters in collaboration with a parameter server that is embedded in an unmanned aerial vehicle (UAV). Different sensors in vehicles capture different types of data, contributing to data heterogeneity. C-V2X communication networks impose additional communication overhead in order to converge to a global model when the sensor data are not independent-and-identically-distributed (non-i.i.d.). Consequently, the training time for local model updates also varies considerably. Using FRL, we accelerated this convergence by minimizing communication rounds, and we delayed it by exploring the correlation between the data captured by various vehicles in subsequent time steps. Additionally, as UAVs have limited battery power, processing of the collected information locally at the vehicles and then transmitting the model hyper-parameters to the UAVs can optimize the available power consumption pattern. The proposed FRL algorithm updates the global model through adaptive weighing of Q-values at each training round. By measuring the local gradients at the vehicle and the global gradient at the UAV, the contribution of the local models is determined. We quantify these Q-values using nonlinear mappings to reinforce positive rewards such that the contribution of local models is dynamically measured. Moreover, minimizing the number of communication rounds between the UAVs and vehicles is investigated as a viable approach for minimizing delay. A performance evaluation revealed that the FRL approach can yield up to a 40% reduction in the number of communication rounds between vehicles and UAVs when compared to gross data offloading.
